Abstract

Die Erfindung betrifft ein aktives Medizinprodukt, bei welchem auf den Bedienelementen (Handschalter, integriertes Folienbedienelement oder dergleichen) mindestens ein Sensor angebracht oder diesen zugeordnet ist, der zunächst einmal detektieren soll, ob der Bediener eine Funktion initiieren möchte. Dieser Sensor könnte beispielsweise als simple monostabile Taste ausgebildet sein (Totmanntaste), oder aber ein sensibles System darstellen, das auf Signale wie Wärme, Feuchtigkeit, Flüssigkeit, Erschütterungen oder dergleichen reagiert, die typischerweise von Bedienern, Patienten, Anwendern oder Betreibern ausgesendet oder verursacht werden. Mit dem so gebildeten Signal soll die Energiezufuhr für die Steuer-, Bedien- und Stellfunktion des aktiven Medizinproduktes freigegeben werden, also zum Beispiel Energiezufuhr für mindestens ein Bedienelement oder mehrere Bedienelemente, Freigabe für die Ausgangssignale und Energiezufuhr für die Logikelemente. Hierdurch wird ein Aktuator, ein Bedienelement oder eine Logikschaltung immer nur dann aktiv, wenn der Bediener das Freigabesignal ausgelöst hat. Hierdurch kann eine Eigenbewegung des Systems, bedingt durch einen ersten Fehler sicher ausgeschlossen werden.The invention relates to an active medical product, in which on the controls (Hand switch, integrated film control element or the like) at least one sensor attached or assigned to it, which initially should detect once whether the operator wants to initiate a function. This sensor could, for example, be designed as a simple monostable button be (dead man's button), or represent a sensitive system based on Signals such as heat, moisture, liquid, shocks or the like responses typically from operators, patients, users or Sent or caused by operators. With the signal thus formed the energy supply for the control, operating and actuating function of the active Medical device are released, for example energy supply for at least one control element or several control elements, release for the Output signals and energy supply for the logic elements. This will be a Actuator, a control element or a logic circuit only ever active when the operator has triggered the release signal. As a result, a The system's own movement is definitely ruled out due to an initial error become.
